The Dazzle is a family of external video capture devices that allow people to record video from analog composite video sources (DVD player, VCR, etc.) over USB (originally parallel). [1] Most models are also capable of recording analog stereo audio.
Depending on the device, the resulting video stream may be conveyed to external circuitry via a computer bus (e.g., PCI/104 or PCIe) or a communication interface such as USB, Ethernet or Wi-Fi, or stored in mass-storage memory in the device itself (e.g., digital video recorder).
Video4Linux (V4L for short) is a collection of device drivers and an API for supporting realtime video capture on Linux systems. [1] It supports USB webcams, TV tuners, CSI cameras, and related devices, standardizing their output, so programmers can easily add video support to their applications.
A frame grabber is an electronic device that captures (i.e., "grabs") individual, digital still frames from an analog video signal or a digital video stream. It is usually employed as a component of a computer vision system, in which video frames are captured in digital form and then displayed, stored, transmitted, analyzed, or combinations of ...
